My name is Thomas Stensitzki and work as a principal technology consultant focusing on the Microsoft messaging and collaboration technologies. I am the owner of Granikos GmbH & Co. KG. My company provides enterprise consulting and training services for Microsoft Exchange, Office 365, and Modern Collaboration.

Since April 2018 I am a MVP for Office Apps & Services.

I hold Master certifications as Microsoft Certified Solutions Master Messaging and as Microsoft Certified Master for Exchange Server 2010. This makes me a subject matter expert for any messaging topic related to Microsoft Exchange, Exchange Online, Office 365 and hybrid configurations. When not working as a consultant I teach Microsoft technology courses as a Microsoft Certified Trainer.
